[Stoves] Six BOX Program

[Frank Shields]

Dear Stovers,

 

Getting Organized with the Six Box Program

BOX 1: Fuel(s)

BOX 2: Fuel manipulation between BOX 1 and BOX 3

BOX 3: Stove(s)

BOX 4: Utensil(s)

BOX 5: Manipulation between BOX 4 and BOX 6

BOX 6: Task(s)

 

The final report conclusion is the fuel used from BOX 1 to do the task in
BOX 6 to come up with a (Fuel / Task) value. Fuel being so variable but all
having the common element Carbon we convert the fuel used to carbon used for
the final result of (Carbon / Task). The body of the report has all the
parameters for each of the six variables (BOXES) that resulted in the
conclusion. That so this process can be repeated by any lab and NGOs can
pick from a list of stoves that have been tested using the fuel and tasks
common to the location.  

 

Example report might go something like this:

 

BOX 1: Fuel used is: sticks, 25 to 30cm long, 10 to 20 % moisture, ~¾ bark
and ¼ split, curve ~ 1 to 5 % length off center, ????  Carbon content to be
determined later if not available or estimated at 44% dw.     

 

BOX 2: How and how frequent the fuel is placed in the stove. As Paul
Anderson pointed out this should be as it will be done in the field with
possibly one person cooking and adding fuel at the same time. A lab
instruction for operating the stove is based on observations.

 

BOX 3: Stoves; name, model number, designer etc. Also within this BOX 3 is
where HHV, LHV, condensation, tar build-up, particles, gas emissions, heat
transfer and other stove research is conducted. The better the workings of
BOX 3 (same for the other 5 BOXES) the better the overall Carbon / Task data
will look. 

 

BOX 4: This is describing the Utensil (pot, pan) used for the particular
stove and task. Size, metal thickness, metal type, cover, etc. 

 

BOX 5: The heat from the stove splits and some go into and through the
Utensil and the rest up the stack. The heat coming through the Utensil hits
the Task. This is where the How and Frequency the cook manipulates the
cooking process to distribute the heat is recorded. Stir the pot of water or
flipping the pancake. Instructions for this should also be based on
observation in the field to instruct the lab. 

 

BOX 6: Completed Task recording quality and how well liked in the field (?)
the process went etc. 

Conclusion is the Carbon used / Task. There can be more than one task during
this process if the stove is kept fuelled to heat a room or for light or to
keep hot coals to make easy to start the next fire. Or this program can be
added on to another Six BOX Program using the left over char as BOX 1. 

 

Just some ideas.

 

 

Thanks
